Ok, it took a little while to work it out, but it is very neat. The case has a nice protective rubbery feel to it...good grip and thin over the control buttons, so you can easily feel your way around.
True...it does not have a screen protector, but you can buy these as another product. I have the screen protector as well, an it works really well with the rubber case (or is it silicon). The protector (not included with the case) is the exact size of the screen, so place it very carefuly to make sure you cover all the screen (unlike me).
Back on the case...the wiring tidy thing is like a false back connected to the middle of the rear of the case by a large red plasic circle, about the size of a 2p coin. You simply plug your earphones into the normal socket and wrap the lead around the plasic 2P circle between the back and the false back...keep wraping until you have the right length of cable you need. There's alittle slit at the other end of the false back for the cable to slide into to keep things neat. As others have said..no instructions, which is surprising. Last thing, I have notice two little holes at one end of the case that must be for sliding a cord through so you can hang the device around your neck or whatever. I haven't tried this, so don't know how secure it is......hope this is usefull!
